Once it has been setup, the attractive and durable screen door remains sealed with magnets, keeping pesky bugs and mosquitoes out and allowing the fresh air of the outdoors in. Whenever you, your children, guests or pets need to go in our out, just walk through the screen and it will open right up, once you are through the center and bottom magnets will snap together, closing the screen behind you.
